Hi folks, this is the special meetup group for the weekly Sunday Blood on the Clocktower games in at BRLO Brwhaus in Berlin. We run beginner-friendly and intermediate-level games throughout the afternoon and evening. **Friendly newcomers of all skill levels are welcome, no experience required!** Our group aims to provide a fun and welcoming space to experience this thrilling game of social deception. **We focus on promoting a positive and fun group atmosphere, where players don’t take themselves or the game too seriously, whether they’re heroically winning or spectacularly losing.** Our players follow the code of conduct for the Berlin Board Gamers group and are expected to treat each other with respect and consideration – “killing with grace, and dying with dignity”. We are usually able to offer two simultaneous games on Sundays. If you are marked as "attending" in Meetup and are in your seat at 15:00, your place is guaranteed for as long as you want to stay. All other seats are first come, first served. We always run at least one beginner-friendly game of the basic version of Clocktower ("Trouble Brewing") throughout the afternoon and evening. We also usually have enough players for a second intermediate-level game. If you are already very familiar with Clocktower, consider also joining our Tuesday meetup for advanced players, when we play with complex custom scripts and characters. Blood on the Clocktower is a deep, mechanical game of murder and mystery, lies and logic, deduction and deception… think Werewolf on steroids. Each player receives a unique secret role and plays either for the good team – the uninformed majority, gathering info and working with others to solve the puzzle – or the evil team, the informed minority, scheming to eliminate good players and protect their demon from execution. In our beginner games no prior experience is expected and we will gladly explain the game rules to any newcomers. We play in English so players should be able to understand and express themselves in English: an exception is possible for one pair of players willing to play together (as a “Revolutionary” pair) where one player can interpret into and out of English. Please let us know in advance if this is the case.

[https://urbanaturetravel.com/event/havel-heights-viewpoints-5apr2026](https://urbanaturetravel.com/event/havel-heights-viewpoints-5apr2026) **SPECIAL OFFER FOR NEW USERS** * 10% New User Discount using promo code: **MEETUP10** * Valid for this trip or any other trips available on our website. **WHY GO?** Berlin is often thought of as a flat city, but Grunewald hides a surprising landscape of wooded hills and sweeping viewpoints. This hike follows sandy woodland trails and quiet paths along the Havel River, gradually climbing through the forest to reach some of Berlin’s best vantage points. We’ll climb the steps of the historic Grunewaldturm before stopping for a relaxed break at Kaisergarten am Grunewaldturm, a traditional beer garden overlooking the river. From there, we continue through the forest and up to the summit of Drachenberg, where wide views open out across the Grunewald and the distant Berlin skyline. It’s a chance to leave the busy streets behind, enjoy some fresh forest air, and spend the day exploring one of Berlin’s most beautiful landscapes with a group of curious explorers. **WHAT ARE SOME OF THE HIGHLIGHTS?** **Grunewald:** Berlin’s largest forest, filled with sandy trails, glacial hills, and quiet lakes. A favourite escape for those looking for nature just outside the city. **Havel River:** One of the major rivers of the Berlin-Brandenburg region. Here the river widens into large lakes and peaceful bays surrounded by forest. **Grunewaldturm:** Built in 1899, this historic observation tower rises above the forest overlooking the Havel. Climb the steps to enjoy wide views over the lakes, woodland, and the distant Berlin skyline. **Kaisergarten am Grunewaldturm:** A classic German beer garden beside the tower. With views across the river, it’s the perfect place for a relaxed break, a drink, or a snack. **Drachenberg:** One of Berlin’s best viewpoints. From the top you’ll see a sweeping panorama across the Grunewald, Teufelsberg, and the Berlin skyline. We’ll aim to reach the summit in the early evening, with the chance of catching sunset — a memorable way to finish the hike. **WHAT IS THE PLAN?** * **10:00 AM-Option A: Meeting in Alexanderplatz S Bahn Station:** Meet at Alexanderplatz station and take the S Bahn to Nikolassee Station. * **11:30 AM-Option B: Meeting in Nikolassee S Bahn Station**: Arrive at Nikolassee station and kick-off with brief introductions before starting our hike into Grunewald Forest * **12:30 PM-Scenic Hike Along the Havel:** Continue hiking the hilly forest trails along the Havel, taking breaks as desired at any of the numerous benches with beautiful lake views. * **03:30 PM-Lunch Break at Grunewaldturm Biergarten:** Arrive at the Kaisergarten am Grunewaldturm Biergarten for a well-deserved lunch and climb the Grunewaldturm * **05:00 PM-Hike Towards Teufelsberg & Drachenberg:** Continue hiking through the peaceful Grunewald Forest and over Teufelsberg towards Drachenberg * **07:15 PM-Sunset Views from Drachenberg:** Reach the top of Drachenberg and take a break to soak up the panoramic views and sunset **WHAT IS INCLUDED?** * Community leader & guide for the entire duration * Access to Google photos album dedicated for this trip for sharing all your amazing pics & videos from the trip. * Access to a WhatsApp group for confirmed participants. **OPTIONAL ADD-ONS:** * Entry to the Grunewaldturm viewing platform is optional.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

Mental Health, how do you understand it? How can you improve it? How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp. This group is hosted by the Dianetics and Scientology Life Improvement Center of Central Ohio.

Come assist Van Buren Shelter (https://ymcacolumbus.org/locations/vanburen) staff in serving dinners and cleaning up on the 3rd Tuesday of each month. Dinner for the women is 5-6 pm and for the families is 6:15-7:15 pm. There is ample free parking available in the shelter's lot. The recommended area to park is in green in the image above. There will be a new entrance for the time being. We are asking all volunteers to enter through the Donation Dock door, the orange mark on the image above. This door is located between the Single Adults and Family Shelter. You will see 2 large garage doors with a large green trash compactor in the center. Please head to the closest garage door to the building wall, with a ramp leading up. There, you will see a door with a sign stating instructions on how to enter the building. Please ring the doorbell, and a staff member will come and escort you into the building. If a staff member takes longer than 5 minutes, please call the front desk at 614-689-2020. This is a new process for us, and we do not want to keep you waiting! We appreciate your patience as we navigate this temporary change. The shelter needs a volunteer count the day before the event so sign-up ends Monday at 4:50 PM. Afterwards some of us go to the Omnipresent Atheists Weekly Meetup in progress to have a bit to eat or drink (http://www.meetup.com/omnipresentatheists/). Volunteers must be 14 or older. Since we will be working around families, the YMCA does not permit volunteering by individuals with convictions for violent or sexual crimes. The YMCA reserves the right to run background checks on volunteers. For questions, comment on this page or contact: Andrew, awhit12@yahoo.com, (614)937-5802 (cell). Please let Andrew know if you volunteer anytime other than our COUNT events so that he can count your hours toward our service record.
